Answer:

X= 8.6666

Explanation:

First multiply ehat is on the outside by the inside.

3×X=3x

3×-4= -12.

Now you have 3X-12= X+14

First add -12 to 14.

Your goal is to get all the numbers on one side and the letters on the other side.

12+14=26.

Now you have 3X=26

To get the X by itself divide 3 on both sides.

X÷3= X

26÷3=8.6666

So your answer is X=8.6666

Answer:

x=13

Explanation:

you have to isolate the variable

3(x-4)=x+14

distribute

3x-12=x+14

subtract 14 from each side

3x-26=x

subtract 3x from each side

-26=-2x

divide each side by -2

13=x

flip sides

x=13

hope this helps!!! :)
